ABSTRACT:
A method for charge sharing between source lines of a pixel array. The method includes the steps of grouping the source lines into pairs, implementing charge sharing if data polarities of a currently and a last scanned row are different; otherwise, in each pair of the source lines, estimating a first and second energy driving the two source lines respectively with and without a preliminary charge sharing, and implementing charge sharing only if the first energy is smaller than the second energy.
